Computer Self-efficacy (CSE) refers to peoples’ beliefs in their ability to use a computer system successfully in support of their work (Compeau and Higgins, 1995; Marakas et al., 2007). As such, external CSE directly depends on the support offered by a system, e.g., in terms of helpfulness or reliability. By contrast, internal CSE is a belief about one’s ability to use a system successfully on one’s own; it reflects the belief that one has the ability to accomplish a work task independently using a computer system (Thatcher et al., 2008).
